Expected and realized accuracy of genomic predictions with RR_GBLUP. Expected accuracies were calculated according to Daetwyler et al. (2010), by considering two approximations for the number of independent chromosome segments (Me): Me1 = 2NeL/ln(4NeL) or Me2 = 2NeL, where Ne is the effective population size and L is the genome length (in Morgans). realized = realized accuracy of GBLUP (average of ten replicates). Five traits were considered: weight at 6 weeks (W6W), weight growth slope (WGS), body length (BL), percentage of CD8+ cells (%CD8+), ratio between CD4+ and CD8+ cells (CD4+/CD8+). Two scenarios of prediction were considered within-family (_within) and across-family predictions (_across).
